A sensor 21 is provided. That is, when the temperature detected by the refrigerant temperature sensor 21 decreases to the temperature detected by the dew point temperature sensor 20, the solenoid valve 19 of the bypass path 18 is opened.

防止することができる。By the way, the absolute humidity of the air in the indoor air passage 1 is greatly reduced by passing through the adsorber 7. However, since it is not completely dry air, if the temperature of the evaporator 3 is extremely low, the evaporator is very low. Condensation occurs on 3. Therefore, in the present embodiment, when the temperature detected by the refrigerant temperature sensor 21 decreases to the temperature detected by the dew-point temperature sensor 20, the solenoid valve 19 of the bypass path 18 opens and the high-temperature refrigerant on the refrigerant discharge side of the compressor 4 passes through the bypass path. Since it flows into the refrigerant inflow side of the evaporator 3 through 18, the temperature of the refrigerant flowing into the evaporator 3 rises, and the temperature of the evaporator 3 is kept higher than the temperature detected by the dew point temperature sensor 20. Therefore, dew condensation on the evaporator 3 can be reliably prevented.
